Memory Module Specification KVR400D2E3K2/1G 1GB (512MB 64M x 72-Bit x 2 pcs.) DDR-400 CL3 ECC 240-Pin DIMM Kit DESCRIPTION: ValueRAM's KVR400D2E3K2/1G is a kit of two 64M x 72-bit (512MB) DDR2-400 CL3 SDRAM (Synchronous DRAM) ECC memory modules. Total kit capacity is 1GB (1024MB). The components on each module include nine 64M x 8-bit (16M x 8-bit x 4 Bank) DDR2-400 SDRAM in FBGA packages. Each 240-pin DIMM uses gold contact fingers and requires +1.8V. The electrical and mechanical specifications are as follows: FEATURES: Clock Cycle Time (tCK) CL=3 Row Cycle Time (tRC) Refresh to Active/Refresh Command Time (tRFC) Row Active Time (tRAS) Single Power Supply of Power UL Rating 5ns (min.) / 8ns (max.) 55ns (min.) 105ns 40ns (min.) / 70,000ns (max.) +1.8V (+/- .1V) 2.592 W (operating per module) 94 V - 0 Note: The module defined in this data sheet is one of several configurations available under this part number. While all configurations are compatible, the DRAM combination and/or the module height may vary from what is described here. However, in no configuration will the module height exceed 1.250" (31.75mm).
